bpo-32604: Add support for a "default" arg in channel_recv(). (GH-19770)
This allows the caller to avoid creation of an exception when the channel is empty (just like `dict.get()` works).  `ChannelEmptyError` is still raised if no default is provided.

bpo-40334: Catch E_EOF error, when the tokenizer returns ERRORTOKEN (GH-19743)
An E_EOF error was only being caught after the parser exited before this commit. There are some cases though, where the tokenizer returns ERRORTOKEN *and* has set an E_EOF error (like when EOF directly follows a line continuation character) which weren't correctly handled before.

bpo-39995: Split test_concurrent_futures.test_crash() into sub-tests (GH-19739)
Now only test_error_during_result_unpickle_in_result_handler()
captures and ignores sys.stderr in the test process.

Tools like test.bisect_cmd don't support subTest() but only
work with the granularity of one method.

Remove unused ExecutorDeadlockTest._sleep_id() method.

bpo-40334: Rewrite test_c_parser to avoid memory leaks (GH-19694)
Previously every test was building an extension module and
loading it into sys.modules. The tearDown function was thus
not able to clean up correctly, resulting in memory leaks.

With this commit, every test function now builds the extension
module and runs the actual test code in a new process
(using assert_python_ok), so that sys.modules stays intact
and no memory gets leaked.

* Avoid flag flip and set results directly.

* Resolve processor in a single function.

* Extract processor handling into a namespace (class)

* Remove _syscmd_uname, unused

* Restore platform.processor behavior to match prior expectation (reliant on uname -p in a subprocess).

* Extract '_unknown_as_blank' function.

* Override uname_result to resolve the processor late.

* Add a test intended to capture the expected values from 'uname -p'

* Instead of trying to keep track of all of the possible outputs on different systems (probably a fool's errand), simply assert that except for the known platform variance, uname().processor matches the output of 'uname -p'

* Use a skipIf directive

* Use contextlib.suppress to suppress the error. Inline strip call.

* 📜🤖 Added by blurb_it.

* Remove use of contextlib.suppress (it would fail with NameError if it had any effect). Rely on _unknown_as_blank to replace unknown with blank.

* Add _PyThread_at_fork_reinit() private function. It is excluded

* threading.Thread._reset_internal_locks() now calls

bpo-39481: Implementation for PEP 585 (#18239)
This implements things like `list[int]`,
which returns an object of type `types.GenericAlias`.
This object mostly acts as a proxy for `list`,
but has attributes `__origin__` and `__args__`
that allow recovering the parts (with values `list` and `(int,)`.

There is also an approximate notion of type variables;
e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`.
Type variables are objects of type `typing.TypeVar`.

lib2to3: Support named assignment expressions (GH-12702)
There are two copies of the grammar -- the one used by Python itself as
Grammar/Grammar, and the one used by lib2to3 which has necessarily diverged at
Lib/lib2to3/Grammar.txt because it needs to support older syntax an we want it
to be reasonable stable to avoid requiring fixer rewrites.

This brings suport for syntax like `if x:= foo():` to match what the live
Python grammar does.

This should've been added at the time of the walrus operator itself, but lib2to3 being
independent is often overlooked.  So we do consider this a bugfix rather than enhancement.

bpo-20526: Fix PyThreadState_Clear(): don't decref frame (GH-19120)
PyThreadState.frame is a borrowed reference, not a strong reference:
PyThreadState_Clear() must not call Py_CLEAR(tstate->frame).

Remove test_threading.test_warnings_at_exit(): we cannot warranty
that the Python thread state of daemon threads is cleared in a
reliable way during Python shutdown.

but is not allocated yet. This is the case immediately after the
module is created and before the module is executed (Py_mod_exec
function). More precisely, these functions are not called if m_size is
greater than 0 and the module state (as returned by
PyModule_GetState()) is NULL.

Extension modules without module state (m_size <= 0) are not affected.

bpo-39360: Ensure all workers exit when finalizing a multiprocessing Pool (GH-19009)
When the pull is not used via the context manager or terminate() is called, there is a system in multiprocessing.util that handles finalization of all pools via an atexit handler (the Finalize) class. This class registers the _terminate_pool handler in the registry of finalizers of the module, and that registry is called on interpreter exit via _exit_function. The problem is that the "happy" path with the context manager or manual call to finalize() does some extra steps that _terminate_pool does not. The step that is not executed when the atexit() handler calls _terminate_pool is pinging the _change_notifier queue to unblock the maintenance threads.

This commit moves the notification to the _terminate_pool function so is called from both code paths.

bpo-38662: ensurepip invokes pip via runpy (GH-18901)
The ensurepip module now invokes pip via the runpy module.
Hence it is no longer tightly coupled with the internal API of the bundled
pip version, allowing easier updates to a newer pip version both
internally and for distributors.

This way, any changes to the internal pip API won't mean ensurepip needs to be
changed as well. Also, distributors can update their pip wheels independent on
CPython release schedule.

bpo-39852: IDLE 'Go to line' deletes selection, updates status (GH-18801)
It appears standard that moving the text insert cursor away from a selection clears the
selection.  Clearing prevents accidental deletion of a possibly off-screen bit of text.
The update is for Ln and Col on the status bar.

We make `|=` raise TypeError, since it would be surprising if `C.__dict__ |= {'x': 0}` silently did nothing, while `C.__dict__.update({'x': 0})` is an error.

Py_LIMITED_API macro is defined.

Changes:

* Add _Py_FatalErrorFunc() function.
* Remove the function name from the message of Py_FatalError() calls
  which included the function name.

Tested internally using an integration test that has run into this a couple of times in the past two years.  With this patch applied, the test is no longer flaky.

bpo-39769: Fix compileall ddir for subpkgs. (GH-18676)
Fix compileall.compile_dir() ddir= behavior on sub-packages.

Fixes compileall.compile_dir's ddir parameter and compileall command
line flag `-d` to no longer write the wrong pathname to the generated
pyc file for submodules beneath the root of the directory tree being
compiled.  This fixes a regression introduced with Python 3.5.

Also marks the _new_ in 3.9 from PR #16012 parameters to compile_dir as keyword only (as that is the only way they will be used) and fixes an omission of them in one place from the docs.
